Git: SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version

[mtkumar82]

Hi,

I had installed git 2.16 version installed with window 7 32 bit. I am using PHPStorm with git integration. Pull, Push was working fine upto 22 Feb 2018. But from 23 Feb 2018 I am getting below error when Pull or Push on git.

Failed with error: fatal: unable to access 'https://github.com/strattas/hos.git/': error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version

May I know plz what issue is it and how I can resolve this?

Thanks

Github has disabled weak TLS protocols: https://github.com/blog/2507-weak-cryptographic-standards-removed

Can you try to run the git pull from the Git bash outside of PHPStorm in order to determine whether this is a Git issue or a PHPStorm issue?

I can confirm I have this same problem using git directly from the ming32/bash console.

$ git --version
git version 1.9.5.msysgit.0

fatal: unable to access 'https://github.com/BigWigsMods/BigWigs.git/': error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version

@jmylchreest You are using an ancient and no longer supported msysgit build of Git. Please update to the most recent release and check again.

[jmylchreest]

Ah, thats interesting thanks. I actually had the new git-for-windows installed but the old version was still there and the git bin from that was being used. Uninstalled it by navigating to the uninstaller in the x86
program files dir, reinstalled the newer version again and it's working correctly now! Could this be the same problem you have @mtkumar82?

Thanks.

@mtkumar82 it would have been a good idea to fill out the bug reporting template (instead of ignoring and deleting it). In particular the output of git version --build-options would have answered @jmylchreest's helpful question.

[mtkumar82]

Hi,
I installed my older version of git and removed all directory from my system and the install git again. I have git version :

git version 2.16.2.windows.1
cpu: x86_64
built from commit: e1848984d1004040ec5199e749b5f282ddf4bb09
sizeof-long: 4

Which I installed on Saturday, But still facing same issue. Not able to pull or commit. Very strange and difficult situation for me..

I even tried with direct command from git command prompt.
$ git push
fatal: unable to access 'https://github.com/strattas/hos.git/': error:1407742E:S SL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version

Still same error.

Plz help me sort out this issue, very urgent...

Thanks

@mtkumar82

Could you confirm you are running a known good version of the Git Credential Manager:

$ git credential-manager version

And also attach the output from this command:

$ GIT_CURL_VERBOSE=1 git push

This will show some additional tracing around how it's erroring

[mtkumar82]

Hi,
Thanks for your reply, Please check below for information.

$ git credential-manager version
Git Credential Manager for Windows version 1.14.0.

@mtkumar82 You're still not getting a TLSv1.2 connection. What's the output of curl --version in Git Bash?

[mtkumar82]

Hello @bbolli , I am still facing the same issue. I learned lot of articles to resolve it, But none help. Below are the details of curl version

curl 7.58.0 (i686-w64-mingw32) libcurl/7.58.0 OpenSSL/1.0.2n (WinSSL) zlib/1.2.1 libidn2/2.0.4 nghttp2/1.29.0

Please let me know what wrong here and how I can quickly resolve this?

Thanks.

[bbolli]

Please let me know what wrong here

Github has disabled the versions 1.0 and 1.1 of the TLS protocol on their servers and your Git insists on using one of the disabled versions.

and how I can quickly resolve this?

That's what we're trying to find out here, so your help and patience is appreciated.

What's the output of openssl s_client -connect github.com:443 -msg? (please wait up to half a minute to let the command time out after openssl prints three dashes ---)

Let me know what wrong here plz?

[bbolli]

So OpenSSL can connect to github, but Git cannot.

Please post the output of cat /etc/install-options.txt and your exact Windows version (cmd -c ver).

PS: When pasting command output, could you enclose the output in two lines, each containing three backticks (see https://guides.github.com/features/mastering-markdown/#examples, the Code examples)? This makes it easier to read. Maybe you could even edit the comment above?

[bbolli]

Could you try CURL_SSL_BACKEND=WinSSL git push?

[mtkumar82]

@bbolli , When I am trying to run the above command , Its giving me below error.

CURL_SSL_BACKEND=WinSSL

'CURL_SSL_BACKEND' is not recognized as an internal or external command,
operable program or batch file.

AND

git push

#

giving below error
fatal: unable to access 'https://github.com/strattas/hos.git/': error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version

Very strange.

[bbolli]

You need to put it all on one line and run it in Git Bash.

[mtkumar82]

Yes I tried it one line also,
fatal: unable to access 'https://github.com/strattas/hos.git/': error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version

[mtkumar82]

May I have your skype id plz, So we can resolve this issue fast ?

[bbolli]

I don't have skype here.

git version 2.16.2.windows.1
cpu: x86_64

This disagrees with

CAfile: C:/Program Files/Git/mingw32/ssl/certs/ca-bundle.crt

For some reason, your allegedly 64-bit build tries to access a 32-bit's certificate bundle.

Maybe first download portable Git from https://github.com/git-for-windows/git/releases/tag/v2.16.2.windows.1 and verify that it is still not working for you from the portable Git's git-bash.exe?

[dscho]

CURL_SSL_BACKEND=WinSSL git push

That should be CURL_SSL_BACKEND=schannel git push.

[dscho]

'CURL_SSL_BACKEND' is not recognized as an internal or external command,
operable program or batch file.

So you are using "Git CMD"? Seriously, it would have helped so much to fill out the issue reporting template. There is a specific question "Do you use Git Bash or Git CMD" for the purpose of making exchanges such as the one you just experienced unnecessary.

The problem here is that you did not understand that @bbolli referred to a Git Bash command. The way this is structured, it calls git push with the environment variable CURL_SSL_BACKEND set to schannel.

In Git CMD, you obviously have to use a different invocation:

set CURL_SSL_BACKEND=schannel
git push

[mtkumar82]

Hello @dscho , Thanks for joining this issue, I am running git bash and , I had tried both your commands.

CURL_SSL_BACKEND=schannel git push.

And

set CURL_SSL_BACKEND=schannel git push

But still getting same error
fatal: unable to access 'https://github.com/strattas/hos.git/': error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version

[dscho]

set CURL_SSL_BACKEND=schannel git push

Certainly you meant to put this in two lines.

fatal: unable to access 'https://github.com/strattas/hos.git/': error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version

This is a very strong indicator that you are not, in fact, calling v2.16.2. Because that is an OpenSSL error message, and v2.16.2 uses a cURL version that would interpret the CURL_SSL_BACKEND=schannel setting to use Secure Channel instead, which would issue a very different error message.

I have a very strong suspicion that the git executable you are calling in this git push call is not at all the same as the one whose git version output you posted.

To verify this suspicion, or to reject it, use Process Monitor while running the push operation, then (after turning off the tracing in Process Monitor), right-click on the git.exe and in the context menu, click on "Properties" to see the absolute path of the git.exe file that was actually called.

Also note that if you have Windows 7 without SP1, your Secure Channel might not be prepared for TLS v1.2. But again, the error message would most likely look very, very different.

[mtkumar82]

is it possible, I can share my screen on Teamviewer and you can check this issue plz?

[mtkumar82]

Path for showing me as below.

C:Program FilesGitusrbinbash.exe

Also note that if you have Windows 7 without SP1, your Secure Channel might not be prepared for TLS v1.2. But again, the error message would most likely look very, very different.
May I know plz how I can check this?

[bbolli]

That should be CURL_SSL_BACKEND=schannel git push.

Way to go, @curl, to require a different string than what is written in the --version output...

[mtkumar82]

How I can change this and what should be the string for curl version? Plz help

[bbolli]

@mtkumar82 Have you tried with Portable Git from https://github.com/git-for-windows/git/releases/tag/v2.16.2.windows.1?

[dscho]

That should be CURL_SSL_BACKEND=schannel git push.

Way to go, @curl, to require a different string than what is written in the --version output...

@bbolli my fault. Sorry. I should really offer a patch that supports "WinSSL" and also makes the values case-insensitive. It does error out, though, with a list of valid values.

[dscho]

Have you tried with Portable Git from https://github.com/git-for-windows/git/releases/tag/v2.16.2.windows.1?

Indeed. I had forgotten that I already suggested this, and missed that this suggestion was also ignored.

[mtkumar82]

To use portable git, Do I need uninstall my current installation of git? Or I can use it with that?

[dscho]

The idea of portable Git is that it does not install anything. Corollary: it does not interfere with anything that is installed already.

[dscho]

Oh, and I just had an idea what could be going on in your setup: maybe somebody set http.sslVersion in your setup. If it is set to an incorrect value, you might be greeted with the reported error message.

To find out, call git config --show-origin http.sslVersion.

[mtkumar82]

Hello @dscho , Thanks for checking this issue, I checked the file and there was
sslVersion = tlsv1.0 in C:Usersamit.gitconfig file, I changed the tlsv1.0 with tlsv2.0, Its not working for pull and push data. Just one issue getting for creating PR , which is still giving me protocol error, Is there any other sslVersion I can change there for Create Pull Request to work?

Thanks,
Jarnail

[bbolli]

@mtkumar82 Just delete this line in the config file, and you should be fine.

[janicemuindi]

Hello there am having the same problem.
fatal error unable to access https://github.com error 1407742E:SSL routines : SSL23_GET_SERVER_HELLO
windows version 8.1
am using cmd to push the app.
kindly help

[bbolli]

@janicemuindi Please follow the steps in this issue to find the problem.

[mtkumar82]

Hello @bbolli ,
I have below code in getconfig file.

[http]
sslVersion = tlsv1.0
proxy =
sslBackend = openssl
sslCAInfo = C:/Program Files/Git/mingw32/ssl/certs/ca-bundle.crt

Do I delete all these lines?
Plz confirm

[mtkumar82]

Hello @janicemuindi , I have the exact same problem. I follow the below steps to sortout this issue.
1) Removed the older version of git and existing directory of git in c:/programer Files/
2) Installed the new version of git, available on git website
3) After complete installation, and help of @bbolli and other, I check the version issue are in file under
C:/Users/yourcomputeruser/.gitconfig
4) I removed the sslVersion = tlsv1.0 from there, and git pull and Push started working for me.
Hope it will helps you.

Thanks

[bbolli]

@mtkumar82 No, just the sslVersion one.

[dscho]

sslVersion = tlsv1.0 in C:Usersamit.gitconfig file, I changed the tlsv1.0 with tlsv2.0

First of all, it is not a good idea to set this sslVersion unless you know what it does (and most often, even not then). So delete it.

Why did you even set it in the first place? Did you read a blog post suggesting this? Or did somebody tell you? I ask because I want to know whether there is erroneous information out there that needs to be fixed because it causes more harm than benefit.

Second, tlsv2.0 does not even exist.

There may be legitimate reasons to set it to tlsv1.2, but your use case is highly unlikely to provide such a reason.

@janicemuindi could you please elaborate your use case quite a bit? Like, you see e.g in https://github.com/git-for-windows/git/issues/1522#issuecomment-368339803 how distressed I got by the sheer lack of information that would have been necessary to help effectively. Please do not repeat that frustrating experience, I really got more than enough of that. Do provide details about your setup. Do provide the version numbers of Git, Git Credential Manager, etc. Do try the suggested invocations to figure out whether you also have such an incorrect http.sslVersion setting, or whether your Git is configured to use Git Credential Manager, or whether it uses a new enough version of it, or, or, or. We have provided tons of helpful advice in this here ticket. Please grab the help we already provided. Don't just throw out a five-liner, ignoring pretty much everything that had been said in this conversation already. That is not only rude, it is also frustrating for everybody involved.

[webuimaker]

Hi,
Thanks bbolli, Mk, dscho

After read all thread and delete sslVersion its working fine.

Thanks a lot. :)

[dscho]

@webuimaker maybe you could answer the question why this was configured at all? Was there any recommendation on some random website?

[dscho]

So is there anybody who thinks that I deserve an answer to my question, and who knows who/what/where recommended setting sslVersion???

[jhchiu1]

Hi,

I encountered this same error using git 1.8.5.6 on mac os x 10.8.5, TLS 1.2. I see this error when after making a commit and then attempting push on both git bash and Pycharm. Since using Git desktop and installing the latest version of git are unavailable options… Any suggestions or work arounds?

Thank you.

[bbolli]

@jhchiu1, please read the thread. The original issue was intuited by @dscho to be an erroneously set http.sslVersion config variable. If your problem is a different one, we need more information.

[dscho]

@bbolli I think @jchui1's problem lies much deeper: they are using a version of Git so old that it is safe to assume that their cURL/OpenSSL combo (used by Git to talk via HTTPS) is also super-old. Too old, probably, to talk TLS v1.2.

Using SSH instead might work around the issue.

[bbolli]

@dscho right, but we don't even know if @jhchiu1 wanted to push to Github or somewhere else.

[dscho]

@bbolli there is unfortunately a lot we don't know because nobody here graces me with any answers to my questions.

[jhchiu1]

@bboli @dscho Thanks for your prompt responses! I am trying to push to a manually created github repo. After work, I will try using SSH. I looked at my gitconfig file and t only lists my email and username... can you provide more details on how to delete the line: sslVersion = tlsv1.0?

[bbolli]

@jhchiu1 Please post the output of git config --list --show-origin here. If this doesn't work (maybe --show-origin isn't supported yet on your Git version) just use git config --list.

[bbolli]

@jhchiu1 You probably have to add a public SSH key to your Github account and switch the remote URL to ssh://. With this old OS and Git, I think that's the only solution.

[jhchiu1]

@bbolli @dscho GREAT NEWS! I was able to push to my GitHub repo!
Thank you very much for all of your help! :)

Here are the steps that worked for me:

ssh-keygen -t rsa -b 4096 -C {[email protected]}

Enter file in which to save the key (/Users/johnsmith/.ssh/id_rsa): /Users/johnsmith/.ssh/id_rsa

Enter passphrase --OR-- (leave empty for no passphrase)

pbcopy < /Users/johnsmith/.ssh/id_rsa.pub

^ Note: pbcopy copies the file's contents to your clipboard.

Now, navigate to your repo's "Deploy keys" setting and paste it.

git init
git remote set-url origin [email protected]:johnsmith/gitrepo.git
git add -A
git commit -m "initial commit"
git push
